iPhone 4s

After we showed you how Siri could be hacked to use a custom proxy and execute custom commands, we knew it wouldn’t be long before additional hacks would start rolling in. [Brandon Fiquett] thought it would be great if Siri could remotely control his car, so he built this functionality into Siri using [Pete’s] proxy software.

The hack relies on the Viper remote start system he had installed in his car, along with a few modules loaded into his proxy server. His proxy server tweaks allow Siri to interpret a preset list of commands such as “Vehicle Start” and “Vehicle Arm/Disarm”, relaying the commands to the Viper SmartStart module.

We imagine that the back-end functionality is not unlike the existing SmartStart iOS app, but it looks like [Brandon] beat Viper to the game since Siri has not been made available to 3rd party developers as of yet.

Check out the video below to see Siri in action, then be sure to swing by his web site for additional videos as well as the code that makes this possible.

[Pete] has an iPhone 4s and loves Siri, but he wishes she had some more baked-in capabilities. While the application is technically still in beta and will likely be updated in the near future, [Pete] wanted more functionality now.

Since Apple isn’t known for their open architecture, he had to get creative. Knowing how Siri’s commands are relayed to Apple thanks to the folks at Applidium, he put together a proxy server that allows him to intercept and work with the data.

The hack is pretty slick, and doesn’t even require a jailbreak. A bit of DNS and SSL trickery is used to direct Siri’s WiFi traffic through his server, which then relays the commands to Apple’s servers for processing. On the return trip, his server interprets the data, looking for custom commands he has defined.

In the video below, he gives a brief overview of the system, then spends some time showing how he can use Siri to control his WiFi enabled thermostat. While the process only works while Siri is connected to his home network via WiFi, it’s still pretty awesome.
